14. The exercise device of claim 9 , wherein said sensing paths are arranged to define a sensing grid extending along said sensing plane.

15. The exercise device of claim 1 further comprising at least one position sensor adapted to detect a presence of the user upon said support surface.

16. A method of measuring one or more parameters associated with a user's vertical jumping ability, comprising:

providing an exercise device including a support surface, a target and at least two position sensors defining sensing paths arranged along a sensing plane located a select distance above the support surface;

adjusting the height of the target and measuring the user's maximum standing reach relative to the support surface;

raising the target to a selected vertical jump height relative to the support surface subsequent to measuring the user's maximum standing reach; and

determining the user's satisfaction of the selected vertical jump height, wherein the determining comprises verifying that both of the user's feet extend vertically beyond the sensing plane.

17. The method of claim 16 , wherein the target comprises a target sensor; and

wherein the determining comprises detecting engagement of the target sensor by the user.

18. The method of claim 17 , further comprising electronically measuring the elapsed period of time between the point at which the user's feet leave the support surface and engagement of the target sensor by the user.

19. The method of claim 17 , further comprising electronically measuring the elapsed period of time between engagement of the target sensor by the user and the point at which the user's feet return to the support surface.

20. The exercise device of claim 9 , wherein said sensing paths and are arranged to define a sensing grid located above said support surface, said at least two position sensors adapted to detect a presence of the user along said sensing grid.

21. The method of claim 16 , further comprising providing a signal indicative of the user's satisfaction of the selected vertical jump height.

22. The method of claim 16 , further comprising adjusting the vertical position of the at least two position sensors relative to the support surface to correspondingly vary a height of the sensing plane above the support surface.

23. The method of claim 22 , wherein the adjusting of the vertical position of the at least two position sensors correspondingly results in the raising of the target to the selected vertical jump height.
